Evaluating a Web-Based Self-Management Intervention in Heart Failure Patients: A Pilot Study.

Background: Web-based interventions may have the potential to support self-care in patients with chronic disease, yet little is known about the feasibility of Web-based interventions in patients with heart failure (HF).

Objective: The objective of our study was to develop and pilot a Web-based self-care intervention for patients with HF.

Methods: Following development and pretesting, we pilot tested a Web-based self-care intervention using a randomized controlled design. A total of 28 participants completed validated measures of HF knowledge, self-care, and self-efficacy at baseline and 1-month follow-up.

Results: Change scores and effect size estimates showed that the mean differences in HF knowledge (d=0.06), self-care (d=0.32), and self-efficacy (d=0.37) were small. Despite email reminders, 7 of 14 participants (50%) of the sample accessed the site daily and 4 of 14 (28%) had no record of access.

Conclusions: Larger randomized controlled trials are needed that attend to all sources of self-efficacy and include more comprehensive educational tools to improve patient outcomes.
